Description

Technical Field

[0001] The utility model relates to the technical field of pipe clamps, in particular to a pipe clamp for a PVC drainage pipe. Background Art

[0002] When using PVC drainage pipes, corresponding pipe clamps are often needed to fix the pipes so that the drainage pipes can be fixed to the building. The Chinese patent announcement number CN219639671U discloses a limit anchor pipe clamp for building drainage PVC pipes, including a first pipe clamp with a semicircular arc shape and a second pipe clamp with a semicircular arc shape. Both ends of the first pipe clamp are fixedly connected to both ends of the second pipe clamp. The inner wall surface of the first pipe clamp and the inner wall surface of the second pipe clamp are fitted with a first pipe clamp band and a second pipe clamp band. Although this technical solution can effectively prevent the drainage pipe from sliding axially, it is necessary to rotate the bolts and nuts on both sides separately to install and disassemble it during use, thereby reducing work efficiency and increasing work burden.

[0003] The Chinese patent announcement number CN210687421U discloses a PVC drain pipe connection clamp that is easy to adjust, including a bottom plate, a first connection seat connected to one side of the bottom plate, a second connection seat arranged on the side of the first connection seat away from the bottom plate, a first connection seat rotatably connected to the second connection seat on one side, a first fixing block connected to the other side of the first connection seat, wherein a second fixing block is connected to the side of the second connection seat close to the first fixing block. This technical solution requires the replacement of different connection blocks to adapt to PVC drain pipes of different sizes when in use, but when replacing the connection block, the connection block needs to be rotated before the connection block can be removed, and then the reverse operation can be performed to fix the new connection block, which is cumbersome to operate, thereby increasing the workload.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, a pipe clamp for a PVC drainage pipe comprises a base 1 and a semicircular plate 2 arranged opposite to each other, both ends of the semicircular plate 2 are fixedly connected with connecting ears 3, and the top of the semicircular plate 2 is fixedly connected with a connecting rod 8. The outer surfaces of the two connecting ears 3 are fixedly connected with threaded seats 4.

[0022] A connection mechanism 5 is installed between the interior of the base 1 and the two threaded seats 4. The connection mechanism 5 includes openings 51 symmetrically opened on both sides of the lower surface of the base 1. A screw 52 is rotatably connected to the top of the opening 51. The top of the screw 52 is threadedly connected to the interior of the adjacent threaded seat 4. The bottom of the screw 52 is fixedly connected to a first bevel gear 53. A rotating shaft 54 ​​is rotatably connected between the two openings 51. A second bevel gear 55 meshing with the first bevel gear 53 is fixedly connected to the outer surface of the rotating shaft 54. Knobs 56 are fixedly connected to both ends of the rotating shaft 54.

[0023] Both ends of the rotating shaft 54 ​​are sleeved with protective covers 57 for rotational connection, and the protective covers 57 are plugged into the inside of the opening 51. The rotating shaft 54 ​​is driven to rotate by turning the knob 56, and the two first bevel gears 53 and the two screws 52 can be driven to rotate at the same time through the two second bevel gears 55, and then the base 1 can be quickly installed and disassembled with the cooperation of the threaded seat 4, without the need for separate operations, thereby improving work efficiency and reducing work burden, thereby solving the problem that the existing pipe clamp needs to rotate the bolts and nuts on both sides separately to install and disassemble, thereby reducing work efficiency and increasing work burden.

[0024] Example 2

[0025] like Figures 1 to 3 As shown, the interior of the base 1 and the interior of the semicircular arc plate 2 are both provided with a semicircular arc pad 6, and the interior of the base 1 and the interior of the semicircular arc plate 2 are both provided with a clamping mechanism 7 that matches the semicircular arc pad 6, and the clamping mechanism 7 includes a rectangular groove 71 opened in the interior of the base 1 and the interior of the semicircular arc plate 2, and a rectangular block 72 is slidably connected to the interior of the rectangular groove 71, and one end of the rectangular block 72 is fixedly connected to the outer surface of the semicircular arc pad 6. A groove 73 is opened on the inner wall of the rectangular groove 71, and a spring 74 is fixedly connected to the interior of the groove 73, and a positioning block 75 is fixedly connected to one end of the spring 74, and one end of the positioning block 75 is hemispherical in shape, and a hemispherical groove 76 that matches the positioning block 75 is opened on the outer surface of the rectangular block 72.

[0026] When replacing the semicircular arc pad 6, you only need to pull the semicircular arc pad 6 directly outward. Since one end of the positioning block 75 and the hemispherical groove 76 are both hemispherical, the positioning blocks 75 on both sides will be directly squeezed out when the semicircular arc pad 6 is pulled, and then the semicircular arc pad 6 can be directly pulled out, and then the rectangular block 72 of the new semicircular arc pad 6 can be inserted into the rectangular groove 71. At this time, the spring 74 will drive the positioning block 75 to enter the hemispherical groove 76, which can limit the semicircular arc pad 6 to prevent it from falling. The operation is simple, thereby solving the problem that the existing pipe clamp needs to be rotated before the connecting block can be replaced, which is cumbersome.

[0027] Working principle: Turning the knob 56 drives the rotating shaft 54 ​​to rotate, and through the two second bevel gears 55, the two first bevel gears 53 and the two screws 52 can be driven to rotate at the same time, and then with the cooperation of the threaded seat 4, the base 1 can be quickly installed and disassembled without separate operations, thereby improving work efficiency and reducing work burden, thereby solving the problem that the existing pipe clamp needs to rotate the bolts and nuts on both sides separately during installation and disassembly to perform installation and disassembly, thereby reducing work efficiency and increasing work burden.

[0028] When replacing the semicircular arc pad 6, you only need to pull the semicircular arc pad 6 directly outward. Since one end of the positioning block 75 and the hemispherical groove 76 are both hemispherical, the positioning blocks 75 on both sides will be directly squeezed out when the semicircular arc pad 6 is pulled, and then the semicircular arc pad 6 can be directly pulled out, and then the rectangular block 72 of the new semicircular arc pad 6 can be inserted into the rectangular groove 71. At this time, the spring 74 will drive the positioning block 75 to enter the hemispherical groove 76, which can limit the semicircular arc pad 6 to prevent it from falling. The operation is simple, thereby solving the problem that the existing pipe clamp needs to be rotated before the connecting block can be replaced, which is cumbersome.
